WAVE FORCES ON CYLINDRICAL MEMBERS AT OFFSHORE STRUCTURE

Abstract

Until now, offshore areas have rarely been utilized because of restrictions caused by waves. To utilize offshore areas more fully, it is necessary to develop technology for construction of offshore structures able to withstand large waves. To achieve this, C.E.R.I, of Hokkaido Development Bureau has carried out in situ offshore experiments to investigate structures in an area with large waves as part of studies funded by Funds for Science and Engineering Development: research on utilization of maritime zones by constructing offshore structures. This project has analysed data of wave forces against circular cylindrical members of offshore structures in a large wave area. This type of data has rarely been reported in the past.
